[beagleboard] Re: Modbus
Thanks Garyamort for the indications. I owe first to verify the typology of the EtherCat and the libmodbus to have explanations on the use. Indeed the use of the modbus consists in the encapsulation as you have specified The other instructions will be me useful to try with the new versions hoping to succeed in getting anything.

[beagleboard] Power supply for BBB
Hey I would like to design the power supply for my BBB. The primary power source is a battery and therefore not constant - depending on load/remaining charge/hooked up to power supply etc... The task is to measure the primary voltage and to supply the board from it. The support will be achieved by a constant output 5V piece. The Voltage supervision must only work between 8-15V - therefore I introduce a voltage splitter to bring it down to 1.8 V (or let's say 1.5 to be on the safe side). Since there can voltage ripple up to 20 V I want to protect the ADC and put a Z-Diode in scheme. https://lh3.googleusercontent.com/-klDTSzzNpGI/UkUo4f64ADI/AAc/xdiVuHQf5cg/s1600/Power.png Now the questions come: - Would you design it accordingly or do I miss something important? - I couldn't find any values on the current drain of the AIN - I kind of need that value to scale the resistors. - Is the Z-Diode fast enough or do I need to introduce some inertia by butting a coil in front of AIN?

I believe that the -a option in mkimage is irrelevant.I think the relevent address in the mkimage command is the entry image address(-e option).This address is used by u-boot to copy the compressed uimage(but without the 64k header i.e zImage only).After this the process is the same as zimage as there is no 64k header.Can you also confirm this. All mkimage does it put a 64k wrapper header on zImage... Nothing more, nothing less.. about the multi-arch thing I think that the problem with using uImage is that the entry address may not lie in the ram space of all the boards that the kernel can support.Right??? It's not lieing it's just that each vendor is free to implements it at a different address, or where ever they want.. See my small list here: https://github.com/RobertCNelson/stable-kernel/blob/master/system.sh.sample#L33 But if this is the case the we will have to change the bootenv of u-boot as we need to load the compressed zimage/uimage somewhere in the ram first.Am I correct? Why change bootenv, the default settings in u-boot for the particular target already work out of the box..

Hi there. I'm trying to follow these instructions to enable UARTS 1, 2, 4, and 5. I think I have the right software version as /lib/firmware contains all of the correct files, but there is no uEnv.txt in /media/BEAGLEBONE/. If I add one with the line capemgr.enable_partno=BB-UART4 and reboot it doesn't seem to do anything. I just reflashed the EMMC with an image I found on this page http://circuitco.com/support/index.php?title=Updating_The_Software, I am using Production Image 2013.09.04. I can enable the UARTs by echoing to the slots file, but I'm lost when it comes to doing this at boot without the uEnv method working. The problem is that by the time the board has booted, I can't enable UART 5 with the echo method as HDMI has already taken over . Does anyone have any pointers as to why there wouldn't be a uEnv.txt file in /media/BEAGLEBONE/?

[beagleboard] GPIO interrupt driver issue
I have written a kernel driver for an available GPIO input pin (P9 Pin15).
At every falling edge it generates an interrupt. The IRQ routing is
currently doing nothing, just returning.
Now I connect a square wave generator to this input pin.
At lower frequencies up to 1000 Hz all works fine.
When I set the interrupt frequency to 15kHz then the system makes strange
things:
Usually it works fine (the CPU load is only 5%),
but sometimes when I send/receive data via ETH then the Linux system hangs
up,
the blue LEDs stop blinking.
When I disconnect the generator, it continues working again.
Looks like that the system is overloaded or runs in a loop or there is a
conflict with the ETH interface ?
But the CPU load is low (I could go up to 100 kHz before htop shows
significant CPU load).
15000 interrupts/s is a very low rate for a 1GHz CPU. So why does it make
problems ?
Any idea what could be wrong ?
Harry
for better readability I have removed all error checking code.
This is the init function:
static int counter_init(void)
{
int res,err;
void *addr;
// setup the GPIO ports, P9-Pin15 as Input which generates an interrupt for
each falling edge
addr = ioremap(AM33XX_CONTROL_BASE + 0x840,4); // get physical port address
iowrite32(0x7 | (2 3) | (1 5),addr); // set the port
mode, mode 7 (gpio), PULLUP, INPUT
gpio_request_one(48, GPIOF_IN, DRV_NAME irq);
irq = gpio_to_irq(48);
request_any_context_irq(irq,input_irq_handler,IRQF_TRIGGER_FALLING,(void*)mydata);
return 0;
}
and the IRQ handler:
static irqreturn_t input_irq_handler(int irq, void* dev_id)
{
return IRQ_HANDLED; // this IRQ was handled
}

[beagleboard] RE: DSP on beaglebone black
Hello, I am building a hearing aid and wish to include DRC (Dynamic range compression), NR (Noise reduction), and destroy Acoustic feedback. Since, I am a college student, I have basic knowledge of linux, but new to programming a MCU. I wish to gather knowledge about how to implement DSP on a BBB.

[beagleboard] Re: Cross compiling an external kernel module for BBB
You need to compile kernel image and module in order to load the module. Linux does not allow loading external modules. When you compile your own kernel, you are able to load any module, since they come from the same source.

Re: [beagleboard] Apple full numeric [Aluminium] keyboard and internal hub does not work
Thanks William and Gerald I will try to get the newer image. I thought 4th Sep, 2013 would be the last stable one but I will look for a newer one. William, I understand what a Serial debug interface is but I have never used one. I am an app engineer, broadening my domain. I will get the cable and start doing that. However, can't I just pull the logs from the file system? I might be wrong but isn't serial debugging for kernel level problem, like the ones which prevent boot at all? One last thing. Should I be looking for a particular kind of keyboard? Beaglebone black has problem out of the box I guess. On Thursday, 26 September 2013 23:11:16 UTC+5:30, William Hermans wrote: Hi Sushant Khanna, I have read about similar issues with all sorts of devices, and as far as I can tell the type of hub used can be a big factor in this situation. First, if you have not tried checking if each device works by its self on the USB host port ( individually ) I would do so now. So, I think in this case I would check to see if the keyboard works by its self with nothing else plugged into it. If it does, then yes this would be a bit of a quandary, as putting this specific keyboard on another hub may make the situation worse. All may not be lost though, there could be a kernel driver module for this specific keyboard, although I would not hold my breathe. You may want to try using a different keyboard / mouse, with a known good working USB hub( if you have such laying around ). Spending money on something and not having that work either . . . yes, I know would not be ideal. Said hub should also be self powered. As to whether you're needing an external power supply I am not sure, and Gerald would know better than I. However we all could use more information to help us know what exactly is happening. Such as the serial debug output at the time the board is powered up with the keyboard and mouse plugged into the USB port. Sometimes, it can not be overstated how handy a serial debug interface can be . . .

Hi Steve, the thing is that I already have a BBB and I need to do rather computationally intensive stuff with it.

[beagleboard] BBB- Disable power via USB
Hi, I need to disable the BBB from booting when usb is connected to the PC. I have an external supply that powers the BBB as well as other things. I would like the configuration such that even if a user connects to the BBB via USB it will not boot until the 5V main power supply is turned on. Looking at the schematics and SRM I know that the TPS65217C senses the USB 5V on its pin 12 and that there is some registers that control how the TPS65217C responds to different signals and these registers are written to via I2C. i just don't know how to do that. The following thread talks about some commands that can be added to uEnv.txt to write to the TPS65217C. I just wish there was more detail on how to do this. https://groups.google.com/forum/#!searchin/beagleboard/USB$20power/beagleboard/yNjXHmb1WnA/nlBoqnetbgcJ Are there easy instructions to modify the registers on the TPS65217C to disable USB powerup? hardware: BBB A5C OS: R.

Re: [beagleboard] BBB- Disable power via USB
We have no instructions on how to break the board.The TPS65217C is designed to power the board from either of these sources, whichever one come first. If 5V is connected it switches to 5VDC when connected. One way to do what you want is to remove the power connection in your cable, cut the wire. However, if you do that, the processor will not recognize the USB as being connected and will not enumerate. On power off, the TPS65217C clears all the registers, so any registers that are set, will be reset on power up.

Re: [beagleboard] BBB- Disable power via USB
Gerald, Thank you for the reply.

Re: [beagleboard] Re: Initializing memory on the BBW using Starterware examples
I just checked, and the last time I compiled an MLO was one year agoto the week! I am using version 2.00.00.07, so I don't know what has changed in 2.00.01.xx. That being said I have a couple more questions: 1) Did you have to create the projects in CCSv5, or did you use the Starterware one (starterware_folder\build\armv7a\cgt_ccs\am335x\beaglebone\demo)? 2) Are you building the bootloader (MLO) and the demo app, or just the demo? 3) What is your demo binary file name? For my application I used the bootloader demo to create an MLO. This MLO setup the beaglebone and then loaded a file called app from the SD card. Once the app was loaded, the bootloader transferred control to it. Louis On Thursday, September 26, 2013 6:49:19 PM UTC-5, Warren S wrote: Hi, Louis Wow, thanks for heeding my call. 1) Yes, I am using the latest Starterware for the AM335x family. The older version actually worked better because I could compile in debug mode while the latest version only lets me run in release mode for the time being. As my TI Applications support adviser noted before turning me over to the forum, the latest version inserts a debug or release folder in the source code location file chain. 2) Yes, I tested it first without any of my own code added to the demo. The print statements were only added later to see where it stopped. 3) I have no problem running the Angstrom Distribution or the Demo using a freshly formatted memory card. Although I am not sure what to expect when I run usb_dev_serial. Perhaps a second com port window? Surprisingly (to me), after Starterware hangs at MMUinit, the MLO/Demo binaries still work after I press the reset button on the board (but not the reset in Starterware).

In general, this just requires some more testing. Any volunteers to try out the sfdisk/tar based solution? Overall, I agree it is a much better approach and I will get started on it as soon as I've submitted the base Buildroot patches upstream.

I just reflashed the EMMC with an image I found on this page http://circuitco.com/support/index.php?title=Updating_The_Software, I am using Production Image 2013.09.04. I can enable the UARTs by echoing to the slots file, but I'm lost when it comes to doing this at boot without the uEnv method working. The problem is that by the time the board has booted, I can't enable UART 5 with the echo method as HDMI has already taken over .

[beagleboard] Re: BeagleBone Black doesn't sometimes start. Only Power LED is on
Same problem here, its showing up in 2 ways. The Beagle Board Black has a power control IC that is sensitive to 5 volt rise time and has frozen up under short brownout situations..in fact, I can freeze it up at will by dropping out 5 V for about 100mS, it will lock up with 3.3 volts turned off even though the 5 volt input is good. Removing the 5 volt input for more than 1 second restores normal 3.3 Volt power and all is good. The other way..I'm still investigating, it refuses to boot about 1 in 20 tries for reasons that are so far unknown. In this instance I have power supply monitoring instruments all over this board, and the power supply controller is working even when the lockup occurs. So I'm mainly interested in the situation where the blue lights are on but the board is not booting. We are running a port of Debian Linux.

We are using Ubuntu Raring 13.04 armhf v3.8.13-bone21 (2013-06-14) on the eMMC (no SD Card). The Beagle Bone is placed in a case and we have connected it to a DC power supply. Sometimes (I would say every 5 to 10 times), when we are plugging in our power supply, the BeagleBone powers on (Power LED is on), but nothing more happens (none of the other four LEDs is on). If we are now removing the power supply and putting it in again, the BBB starts normally. I guess the power supply is strong enough: 5A@5V. Thanks for your help in advance.

[beagleboard] Beaglebone Black and Chipsee 7 LCD running Android
I am going to purchase a Beaglebone Black and the Chipsee 7 LCD that is shown running Android. I have see a lot of downloads for different Android images that will run on the different Beaglebone boards. I would like to make sure i get the right image and source code. Can someone point me to the best place to get an image that will just come up in that config and then also the source so I can build it myself?

I am just learning this stuff so I don't really know what I am missing. Someone told me that the 'standard capes' may be controlled from the kernel rather than from the dts files in the /lib/firmware/ folder, and the /lib/firmware/ folder isnt even mounted at the point the kernel version kicks in. Is this true? If it is, does it require a kernel rebuild in order to change something like the PWM frequency? Is it possible to apply a patch or something rather than having to rebuild the kernel? If so, how is this done? I even went to the extent of changing the EEPROM content of one of the CAPES I have, and then edited a dts file with the same name and part number inside, and then tried to force the cape to be loaded after it had started up by using the uEnv.txt, but that didn't work either.

And putting such a script together with busybox into an in-kernel initramfs, and people would just have to build a card with one file, the uImage. I still like having autorun.sh such that the script can be easily customized without rebuilding. Of course, MLO and u-boot.img are also required. The discussed Buildroot-based image is using initramfs. As long as the eMMC still works (the first partition there is ok), there is no need for mlo and u-boot on the sd-card. Seems like some work is required here to create the logic to make sure each partition is tar'd. Also, the restore script needs to be created. In general, this just requires some more testing. Any volunteers to try out the sfdisk/tar based solution? To restore such a tar, use tar xpjf emmc.tar.bz2 -C emmc --numeric-owner after you've created or formatted and mounted the partition. And don't forget that --numeric-owner on restore, otherwise bad things might happen.
